In the present work, a surfactant-assisted convenient extraction method was developed for the isolation of trimyristin from nutmeg. Commercially available monomeric surfactants and novel readily synthesized cationic dimeric surfactants were used as auxiliary chemicals. The improved isolation method herein revealed that the combination of dimeric surfactant with n-hexane allows selective extraction (without colored polar components of nutmeg) and maximum yield of triglyceride. Besides, the developed method is more practical than existing protocols and provides higher yields of trimyristin in a short period.

Novel cationic gemini surfactants with a hydrophilic oligo-oxyethylene spacer group were synthesized and their physicochemical properties were identified. Computational studies for these compounds were also performed; molecular geometry, frontier molecular orbitals, and quantum chemical parameters were calculated using density functional theory (DFT). After exploration for catalytic activity, it was found that these surfactants can efficaciously accelerate the [3 + 2] cycloaddition reactions in reversed phase micellar media.A Hitachi 3100H dual beam spectrophotometer (Tokyo, Japan) was used for spectrophotometric analysis.
